What is Biology

Simply said, biology is the study of life.

Biologists now agree that life is a product of a certain set of processes that arise from the arrangement of matter. 

Biologists have compiled a list of features that define the “set of life processes” shared by all organisms as living:  The living:

  • Use up stuff and power.
  • To have offspring; to perpetuate one’s genes.
  • Evolve and expand.
  • Demonstrate inherited differences or variants.
  • Are well-suited to their natural habitat.
  • React to external influences.

The scientific nature of biology has led to the categorization of life’s defining features into the following categories:

  • Harmony and Variety
  • Constancy in Genealogy
  • Characteristics of Human Nature
  • Harmony between Form and Operation
  • Organism-Environment Interactions

All of the Life Science classes have a common thread of these key ideas.

Human Body Project Ideas

Rate of cognitive decline in different elevations.

Oxygen partial pressure decreases with altitude, challenging blood oxygenation which may affect brain function. If you’ve ever felt some altitude sickness, then this is exactly what’s happening. This is because the atmospheric pressure decreases at higher elevations, leading to a decrease in the partial pressures of the gasses in the air, including oxygen. And of course, oxygen is needed for us to function. What is the effect on brain health/ cognition in sudden increased elevation: say, climbing Mount Everest? Does chronic exposure to high elevations increase the likelihood of dementia? In this project, a meta-analysis of published works examining the effects of altitude on cognition would be conducted.

Building a Blood Vessel

Use online graphics to illustrate how a blood vessel forms. Blood vessels are structures that carry blood and are responsible for transporting nutrients and oxygen throughout the body. There are three main types of blood vessels: arteries, veins, and capillaries. For this project, complete a literature search to understand what is known about blood vessel growth. Then, utilize this information to generate a graphic with no words to demonstrate how the vasculature (network of blood vessels) forms. The goal of this project is to explain science without using text and therefore make it more available to a larger community.

Regulation of Circadian Clocks

Sleep is known to be governed by two distinct processes: a circadian clock that aligns sleep and wakefulness to the solar day and the sleep homeostat that encodes for sleep debt as a compensatory mechanism against sleep loss. You’ve most likely heard about circadian rhythm and our body’s internal clock, and circadian regulation of sleep is a fundamental process that allows animals to anticipate sleepiness or wakefulness consistently every day. These mechanisms can be regulated in multiple ways: at the gene, protein, gene, and clock neuronal level. In this project, we will focus on 1) how to efficiently digest primary and review articles to compile and condense information, 2) investigate how circadian clocks are regulated at these different genetic levels, and 3) try to effectively summarize the information we've gathered. We can present this information in a variety of ways, and what the final product looks like is up to you.

The Biology of Aging

Aging is the number one risk factor for a variety of diseases including cancer, neurodegenerative disease, and loss of hearing/sight. We are only now beginning to truly understand the process of aging and have even started to uncover ways that we could stop, or potentially reverse, the effects of aging. What are the hallmarks/signs of aging? How do researchers study 'aging'? How does human lifespan and aging compare to the rest of the animal kingdom? Is it possible to stop or reverse the effects of aging? What advancements are being made related to this? We could explore these questions or brainstorm others you might have about the biology of aging.

Animals, Plants, and Nature Project Ideas

How genetically engineered mosquitoes are reducing rates of vector-borne diseases such as zika.

Many countries are already releasing millions of genetically engineered mosquitoes into the wild every week. These mosquitoes have been modified to reduce their ability to transmit disease-causing pathogens like dengue fever, Zika, and malaria, and are sent into the wild to mate with disease-carrying mosquitoes. However, this is still controversial as some people are concerned about the unintended consequences on the environment. What could be the potential pros and cons for this? The project will mainly focus on doing meta analysis of articles and watching informative videos to understand how/why genetically engineered mosquitoes can be used to reduce rates of different diseases. Students will have the chance to use critical thinking and do in-depth research on genetic engineering techniques, how scientists determine breeding rates and number of insects released, and epidemiology of different bloodborne diseases.

Idea by mentor Vanessa

Efficacy of Marine Protected Areas

Marine protected areas (MPAs) are areas of ocean or coastal waters that are set aside for the conservation and sustainable use of marine resources. These areas are established by governments, NGOs, or other organizations, and they can take different forms, from fully protected "no-take" zones to areas with regulated fishing or other activities. Marine protected areas have the potential to guide sustainable resource management and protect biodiversity, but have a host of reasons for why they are not currently effective. Explore reasons for why MPAs may not be effective. Then develop a framework for mapping, modeling, and implementing an effective Marine Protected Area.

Bioinspiration: Do animals hold the answers?

Can the toxins produced by frogs help us fight antibiotic resistant bacteria strains? How can understanding how lizards and newts regrow their limbs help us improve wound treatment? Why do tilapia skins help with burns? Discover the role of animals in the development of modern medicine as well as its potential. Are there any ethical concerns with these developments and findings? If so, what are they and do they matter? Share your findings in a research proposal, article, or presentation.

A Reef’s Best Frenemies

Coral reefs are in global decline. A primary cause of this is "coral bleaching" which results in the white reefs we often see in the news. Coral bleaching is actually the breakdown in the partnership between the coral animal and tiny, symbiotic algae that live within its cells. Corals and algae have a variety of thermal tolerances which are likely decided by genetic and environmental factors. However, despite how important this relationship is, it's currently very poorly understood. This project would review existing literature on the symbiotic partnernship and try to identify factors that predict bleaching and thermal resilience.

The Amyloid Hypothesis: Sifting through the controversy

For many years, scientists have thought that amyloid beta was the protein responsible for a patient developing Alzheimer's Disease symptoms. This "Amyloid Hypothesis" is now being questioned in light of current clinical data. Recently, drugs have been developed that reduce amyloid beta in patients. Surprisingly, the drugs worked in reducing amyloid beta, but it did not result in the slowing of disease pathology. Does this mean that the amyloid hypothesis is incorrect? Is amyloid beta less important in the progression of disease then what we once thought? This research project aims to explore the issues with the amyloid hypothesis and to assess where we stand in our understanding of amyloid beta's contribution to Alzheimer’s.

Idea by mentor Helen

Sleep Disruption Profiles in Various Mouse Models of Alzheimer’s

Alzheimer's disease (AD) has been studied for decades but we are no closer to understanding the mechanisms of the disease. Because of the vast number of researchers studying AD, there are numerous models used to study the disease. All these models have different sleep profiles, phenotypes, disease onsets, sex differences etc. Therefore, in this project we will compile a document based on extensive literature review about the various models there are. We will focus on sleep profiles in these animals with an emphasis on male and female differences. This information is valuable because it is important to know which model is best to use to answer your scientific questions and there is a lot of criticism (by other scientists) that can be brought on by the model chosen so you need to be able to justify your choice. This project will also introduce you to the world of AD research and some of the gaps in knowledge in the field.

Rethinking The Treatment Of Neurodegenerative Diseases

Neurodegenerative diseases affect millions of people worldwide. They are conditions that affect the nervous system, particularly the brain and spinal cord, and examples include Alzheimer’s and Parkinson’s. While billions of dollars have been spent trying to find treatments for the disease, very few drugs and therapies have had a meaningful impact on slowing down disease progression. This is often because by the time someone is diagnosed with a disease, it has progressed too far for a treatment to have a substantial effect. Some recent approaches to treatment have turned to looking for early indications of the disease (termed "biomarkers") that can occur before the onset of symptoms. By diagnosing disease and beginning treatment before symptoms arise, these treatments could have a more profound effect in slowing down the progression of disease. Students could review the recent progress being made on identifying biomarkers for neurodegenerative diseases, and either write a paper or even record a podcast on their findings!

Idea by mentor David

Genetics Project Ideas

Height and genetics: nature or nurture.

How much do your genes determine your height? How much do nutrition and environmental factors play a role? What gene variants are implicated in height differences and what is the role of epigenetics? Epigenetics is the study of heritable changes in gene expression or cellular phenotype that occur without changes to the underlying DNA sequence. These changes can be influenced by diet and lifestyle. We will access and analyze an open dataset on twins to estimate the correlation between monozygotic twins (who have the exact same DNA) and height. You will learn to use R to open a dataset, analyze data with statistical methods such the student’s t-test, and display your data as graphs and charts. Finally, you will learn how to make a research presentation on height and genetics, describe the research methods, and present the data in a compelling and thorough way.

Idea by mentor Adeoluwa

The World of Personalized Medicine

Similar to our fingerprints, our genetic code is also unique to each individual person. Our genetic code is what determines our hair color, height, eye color, skin tone...just about everything! For those that develop diseases such as cancer, their genetic code found inside the malignant cells that comprise a tumor may also be unique to them or to certain groups of people with similar mutations (the drivers of disease). So why is it that we treat each person the same way even though the genetic drivers of that disease may be disparate? The world of Personalized Medicine is new and exciting and looks to circumvent this problem. Personalized Medicine (also known as precision medicine) uses the genetic code of a patients disease to guide treatment options that prove to be highly efficacious. Together, lets write a review on a disease of your choice that could benefit from Personalized Medicine based on current literature and research.

General Biology Project Ideas

Teach a biology concept two ways: to your fellow students and to the general public.

One of the best ways to learn is to teach. Choose a biological concept that interests you and prepare a lesson and or demo on it. The format should be a video recording of yourself teaching (a la Khan Academy or a Zoom class), but the other details are up to you. Consider incorporating a demonstration (e.g. how can you use items from your kitchen to illustrate properties of mixtures?) or animation (e.g. to illustrate molecular motion). Also consider how you will check that your students understand the concept(s) and/or skill(s) you have taught them. Prepare and record two versions of your lesson: one intended for your peers and one for the general public. How will the versions differ to reflect these different audiences? You will learn what it's like to teach, gain a much greater understanding of your chosen concept(s)/skill(s), and learn how to communicate science to different audiences.

List of biology project topics for class 11, vermicomposting, blood groups, sample biology project class 11.

Here are the two types of Biology Projects for students:

Source based Project: In this type of biology project, students can choose a topic and collect the information through different sources such as books, websites, and journals.

Research Project: In this type of biology project, students are required to perform the scientific experiment in school laboratories. Students must follow proper procedures and obtain the results on their own research. The results obtained through the experiments must be included in the conclusion of the project.

Biology Project Ideas for Class 11 Students

Here are a few biology class 11 projects explained in detail:

Aim: This project is about the various components of Food. Food is a nutritional material taken for growth work, restoration and preservation of life cycles by an organism. For living creatures, food is a kind of power. We have to feed to provide us with energy known as staple foods. Nutrition is the analysis of food material compositions and the amounts of food materials needed by our body for growth, maintenance and survival.

Theory: Some diets have more sugars, and others may have more fat. Many foods contain all the main nutrients but in different proportions, such as sugars, fats, proteins. So we will ensure that our body receives all the necessary nutrients in sufficient amounts by consuming a range of various foods.

  • Carbohydrates
  • Dietary Fiber

Requirements: The above requirements are needed in edible forms to classify the components of food.

Aim: The aim of this project is about Pollution, of different forms, which has a major impact on the environment and culture. About 4.2 million deaths per year are a product of external air pollution, according to the Health Organization. In countries where air quality crosses WHO guideline thresholds, ninety-one percent of the world ’s population now lives.

Theory: Pollution need not necessarily be caused by organic compounds such as particulates (like smoke and dust) (like smoke and dust). Forms of energy such as vibration, heat or light may also cause emissions. These pollution-causing compounds are considered contaminants. Pollution affects the ecosystem equilibrium, even in minuscule numbers. Pollutants will work their way up the food chain to find their way into the human body finally. To discover the forms of emissions and their effects, read on.

Aim: This project is about the Non-Conventional Sources of Energy. Energy is one of the main parts of the economic infrastructure, being the fundamental input required to support economic development. A close association exists between economic growth and the use of oil. Renewable electricity sources are also considered non-conventional energy sources. 

Renewable supplies that are refilled continually by natural cycles. Examples of alternative energy sources include for example, solar energy, wind energy, bio-energy-biofuels generated sustainably), hydroelectric generators, etc. A method of renewable energy transforms power from sunshine, wind, tidal currents, sea waves, convective energy, or biomass into a form that can be used, such as heat and electricity.

Theory: The more industrialized a nation is the larger the per capita intake of electricity, and conversely. Human culture depends on numerous energy sources. It is possible to categories the two main energy sources under: 

  • Conventional Sources
  • Non-Conventional Sources

Aim:  The Human Genome Project was a government financed 13-year initiative begun in 1990 with the goal of identifying within fifteen years the DNA sequence of the whole heterochromatic genetic code. The Human Genome Project was treated with skepticism by many individuals in its initial periods, particularly researchers and theistic evolutionists alike.

Theory: The Human Genome Project is divided into two to discuss the universal genome sequence on the basis of the information obtained from yeast and worm studies (IHGSC, 2001). The first step, called the shotgun process, differentiated human chromosomes into sufficiently sized DNA segments, which were then subsequently subdivided into compiled smaller, alternating DNA fragments.

Aim: This project is about Malnutrition. Every living organism needs food for its sustenance on earth, which is very important for carrying out its mentally and physically related activities, development and growth. Man needs such nutritional requirements such as sugars, proteins, carbohydrates, vitamins, nutrients, starch, and water in the proper proportion and adequate quantity for natural progress and expansion that he gets from the food he consumes. A healthy diet is considered a meal that contains all these important nutrients in the right proportions.

Theory: The loss or even imbalance of any of these in the diet of individual results in eating disorders, which can be collectively considered malnutritional disorders. Malnutrition is the disease in which persons become poor and ill due to inadequate and unbalanced nutrition. Due to hunger, lack of schooling, misinformation and regular pregnancies, a substantial number of individuals in our nation and other developing nations suffer from malnutrition.

Aim: This project is regarding Sickle Cell Anemia and its Prevention. The most frequent cause of sickle cell disease is sickle cell anaemia (SCD). SCD is a severe condition in which the body creates red blood cells that are sickle-shaped. “Sickle-shaped” means that like a crescent, the red blood cells are shaped.

Theory: There are disc-shaped regular red blood cells and they look like doughnuts without holes in the middle. They pass through the blood vessels with ease. An iron-rich protein called haemoglobin is present in red blood cells. There are stiff and sticky sickle cells. The blood vessels in the brain and other organs appear to block blood flow. Pressure and organ injury can be caused by the blocked blood supply. It may also increase the risk of infection as well.

Aim: This is the Monsoon of India Project Study – Our nation is a land of great weather diversity. Seasonal fluctuations as well as variations in both day and night are broad. In weather, these changes are found. A word derived from the Arabic word ‘mousam,’ which implies season, for monsoon use.

Theory: The four months of June, July, August, and September are at the centre of the rainy season in almost all of India. This is the wet season. But it continues to decline from south to north and from east to west. It is hardly two months in the remote northwest. During his time, between three-fourths and nine-tenths of the total rainfall is concentrated.

This may give one an understanding of how it is spread unevenly over the year. By early June they are high enough to draw the trade winds of the southern Hemisphere, the low pressure levels over the north – western plains are further exacerbated. They cross the arctic circle from the Indian Ocean and reach the Bay of Bengal and the Arabian Sea, only to be caught up in the air circulation over India. These south-east trade winds are of oceanic origin.

Aim: By applying manures and fertilisers to the soil of crop fields, the lack of plant nutrients and organic matter in the soil is compensated for. The primary sources of plant nutrients are both manure and fertiliser, so they are used in crop growing.

Theory: In addition to water CO2 and sunlight plants, no elements were required for their growth. These are classified as nutrient elements. From the salt of these elements found in the soil, plants receive their elements. But soil in these elements becomes low after prolonged cultivation of plants. The material applied to the soil to cover up the shortage of the vital components was called fertilisers by increasing soil fertility.

Manures are fertilisers that are natural. They are bulky sources of organic matter that provide small amounts of nutrients but huge amounts of organic matter. Manures include farmhouse compost (FYM), manure, biofertilizers, agricultural residues, etc.

Aim: Trees are an integral part of the Earth’s biosphere. In the life of man, they play an important role. Children play under them and in their cool shade, weary travellers refresh themselves. They’re bringing us fruit to eat and burning firewood. In order to build houses and furniture, we need trees.

It was a tree in a woodland on the slope of a hill. Perhaps the furniture in your classroom is made from trees that once flourished in the Assam or Kerala forests. Trees thus supply us with all of life’s conveniences.

Theory: Trees do a lot more than offer us the conveniences that we have described. They continue to sustain the survival of man by providing the world with oxygen that is important to live. When animals breathe and objects combust, carbon dioxide is the fuel the plants consume. The oxygen in the air is continually taken up and converted into carbon dioxide. 

The leaves of plants (in fact, of all green plants) absorb this carbon dioxide and decompose into carbon and oxygen with the aid of sunlight. The carbon is used to make starch 70, and the oxygen is released into the air, eliminating the animals with the chemicals used. But this would soon mean the animals would die for lack of oxygen.

Aim: The atmosphere on Earth has changed several times in the past. From the south, tropical forests have expanded into more temperate regions (or milder, colder climates). Millions of years later, polar caps extended from the north, surrounding great glaciers in most of the northern United States, Europe and Asia. Almost all scientists today consider that human activities are altering the world.

Theory: The air inside of a greenhouse remains warm under bright sunlight. The greenhouse glass makes light energy and some of its heat energy into the sun. Within the greenhouse, this heat builds up. You were only showing a slight greenhouse effect. What will occur if the Earth’s atmosphere shifted by this greenhouse effect? 

What occurs inside a car parked in the sun is another type of a greenhouse. The light and heat of the sun gets inside the vehicle and like the plastic bag surrounding the jar, is stuck inside. Within a vehicle, the temperature can reach over 120 degrees Fahrenheit (49 degrees Celsius).

Requirements: Two identical glass jars, 4 cups cold water, 10 ice cubes, One clear plastic bag and a Thermometer.

Best Biology Project for Class 11

Biology is a vast subject and has a vast range of concepts when it comes to making projects. Almost all branches of Biology are equipped with learning and experiment. Discussed below are some of the popular Biology project for class 11th with required materials.

Vermicomposting is a biological process of making use of biodegradable waste to make manure which is seen as a sustainable alternative to chemical fertilizers. The process involves earthworms and microbes that decompose plant waste into manure when conducted under the suitable environment. It can be easy and interesting Biology project for class 11th. There are two methods of vermicomposting—Bed Method and Pit Method. Bed method is more advanced and is widely used while the pit method is lesser used due to poor aeration and waterlogging. As such, there are no specific materials that you need, a large bin or a tank is required to store the waste and earthworms are to be put in. The temperature is to be maintained for which the tank can be covered with polythene or dry grass. 

Blood is connective tissue and is crucial in the transportation of oxygen to the cells. As per the ABO blood grouping system invented by Karl Landsteiner, there are four types of blood groups which include A, B, AB and O. All these blood groups are determined by their antigens and antibodies. It is important that the blood group of both the donor and receiver should match during the transfusion to avoid a life-threatening situation. The aim of the project would be to understand the basics of blood grouping system. This can be a very exciting Biology project for Class 11 as it requires a good amount of lab work and handling lab equipment.

Aging and stress.

The team focuses on studying the effects of phytohormones and other natural compounds on various parameters related to stress, aging and age-related diseases. The candidate compounds are evaluated in both human primary cell cultures and Caenorhabditis elegans . The expected indications include skin aging, neurodegenerative diseases and sleeping disorders. In the fields of dermatology and cosmetics, we are interested in identification of compounds for the treatment of pigmentation disorders (melanogenesis assays) and psoriasis (keratinocyte differentiation assays). We are also developing cytoprotective compounds with the improved skin bioavailability. Bioinformatic and cheminformatic approaches are used to identify both candidate compounds and molecular targets.

Pharmacognosy and Metabolomics

The primary goal is the search for new biologically active metabolites or biomarkers in plants, fungi, bacteria and other organisms. Active compounds are identified by metabolomic and bioinformatic methods whose development is also a research interest of this group. This is represented by the development of computational tools and software for processing of LC-QTOF-MS data and identification of active metabolites. In cooperation with other groups, compounds with antiinflammatory, antioxidant, antiproliferative, antimicrobial and anthelmintik activities are investigated. A special interest is also paid to the effect of low molecular weight metabolites on the growth, development and reproduction of plants.

Medicinal Chemistry

Phosphorylation is a universal mechanism for regulating the structure, localization, activity and stability of proteins involved in virtually all cellular processes. It is estimated that 10-50% of proteins can be phosphorylated, often multiple times. Phosphorylation is catalyzed by enzymes called protein kinases and their changes can cause many diseases and disorders including cancers. Genes encoding protein kinases tend to be mutated, amplified and translocated, which in turn significantly alters cell behavior and contributes to tumor transformation. The understanding of these molecular changes has initiated the development of low molecular weight inhibitors of protein kinases, which can be used not only as tools in cell biology, but especially as drugs for cancer.

The development of protein kinase inhibitors as potential antitumor drugs is also taking place in our laboratory. We systematically design, prepare and study compounds based on purine and its isosteric heterocyclic systems, such as pyrazolo[4,3- d ]pyrimidines, imidazo[4,5- c ]pyridines or imidazo[1,2- c ]pyrimidines. Some of our inhibitors show nanomolar activity in both cellular and murine models of cancer. We focus not only on usuall competitive inhibitors, but also on modern modulators of kinase stability based on targeted degradation by PROTAC technologies. The enzymes studied include, in particular, cyclin-dependent kinases (CDKs) and the receptor kinases FLT3 and PDGFR.

Several protein kinase inhibitors are now commonly used as drugs, however, many oncological diseases still rely on conventional cytostatics, the use of which is accompanied by unpleasant side effects. Therefore, we consider this area of ​​research to be very attractive and the development of protein kinase inhibitors on less studied heterocyclic systems is one of our current research intentions.

Currently, the incidence of many neurodegenerative diseases, including in particular Alzheimer's, Parkinson's and Huntington's disease or amyotrophic lateral sclerosis, is increasing. Current symptomatic treatment only provides relief of the symptoms of the disease. Within our group, we focus on the development of in vitro models, mainly Parkinson's disease, but also models involving aspects of the pathology of Huntington's or Alzheimer's disease on human neuronal and glial cell lines. Simultaneously with neurodegeneration, we also deal with models of neuroinflammation. We test compounds from various groups on the above-mentioned models, especially purines and azapurines, steroids including oxysterols, triterpenes, but also natural plant hormones or extracts. The active substances are analyzed for their effect on the production of superoxide radicals, activation of apoptosis or non-apoptotic death, mitochondrial membrane potential and the formation of mitochondrial pores of transient permeability. For the best substances, the mechanism of action is studied by pharmacological modulation of signaling pathways associated with nuclear receptors, adenosine or cannabinoid receptors and neurotransmitter receptors. Furthermore, the effect on proteins or enzymes associated with the neurotransmitters acetylcholine, glutamic acid and β-aminobutyric acid, with oxidative stress, mitochondria, but also with kinases (e.g. protein kinases A, B and C) is studied. An integral part of the study of neuroprotective effects of compounds is the analysis of changes in the concentration of amino acids, neurotransmitters and their metabolites as biomarkers of neurodegeneration or neuroprotection. Such an identified compounds, which show strong neuroprotective effects with minimal toxicity, could become new candidates for the treatment of neurodegenerative diseases after subsequent in vivo evaluation.

Natural Compounds

We are searching for new natural compounds as a model for new generation of drugs derived from these substances. Biological activity of natural products and their derivatives in normal and cancer cells is studied. We are working with cytotoxic, antiproliferative, proapoptotic, antiangiogenic and anti-inflammatory properties. Mostly steroid compounds are investigated, such as brassinosteroids, triterpenes, cardenolides, saponins, betulines, androstanes, other steroids; further then alkaloids and plant extracts.

We are studying cytotoxic effect of our compounds and their synthetic analogues in human cancer and normal cells. Moreover, natural compounds can inhibit proliferation, induce apoptosis or influence the cell cycle. We are searching also for the mechanism of action in different cell types. In addition, we are developing assays with human steroid receptors (AR, ER, PR, GR, MR, VDR). Based on the results from molecular docking we are choosing compounds for additional biological testing according to best binding score.

Creation of new blood vessels, angiogenesis, is necessary for development of organs, but also for growing of solid tumours and metastasis. Antiangiogenic therapy covers inhibition of proteolytic enzymes cleaving extracellular matrix surrounding existing capillaries, inhibition of proliferation of endothelial cells, migration and induction of apoptosis of these cells. Effective antiangiogenic inhibitors blocking tumour growth could serve for new generation of anticancer drugs.

Treatment of inflammation-related disorders by natural products is still in high demand by pharmaceutical companies due to the lack of effective anti-inflammatory drugs. The relative dearth of currently available anti-inflammatory drugs stimulates a search for new active substances. New active anti-inflammatory natural compounds or extracts could be find in plants, mushrooms, marine organisms, insect and its products. Newly isolated, identified or derivatized compounds are studied for their biological activity. Using correlation metabolomics we are able to find active compounds from extracts. Anti-inflammatory properties are deeply investigated for their mechanism of action and pharmacological activity. Natural products serve as huge pool for new potential anti-inflammatory compounds. Products coming from nature with anti-inflammatory activities could serve as a template for new derivatives based on this natural wealth.

Structural Biology

The research group has a long-term interest in studying the function of proteins in vitro and in vivo , their structure and binding interactions with ligands (metabolites). The research is focused on two major thematic areas:

The first topic represents a superfamily of plant and human aldehyde dehydrogenases (ALDHs), which oxidize biogenic and xenobiotic aldehydes using NAD(P)+. Aldehydes are highly reactive compounds and they are generated during the metabolism of carbohydrates, vitamins, biogenic amines, amino acids, steroids and lipids. ALDHs are generally considered as detoxifying enzymes by participating in the adaptive responses to abiotic stress and eliminating aldehydes. In recent years, we have characterized the plant families of ALDH2 (PDB ID: 4PXL , 4PZ2 ), ALDH7 (PDB ID: 4PXN ), ALDH10 (PDB ID: 3IWK , 3IWJ , 4I8P , 4I9B , 4IQ8 ), ALDH12 (PDB ID: 6D97 ), and ALDH21 (PDB ID: 5MZ5 , 5N5S , 5MZ8 ) as well as human ALDH7 and ALDH9 (PDB ID: 6QAK , 6QAO , 6QAP ).

The second topic comprises enzymes and proteins involved in the metabolism and perception of plant hormones cytokinins, which regulate basic plant processes including cell division, development of meristems, stem, roots, seeds and senescence. These are families of cytokinin oxidase/dehydrogenase (CKO/CKX, PDB ID: 4O95 , 3S1C , 3S1D , 3S1E , 3S1F , 4MLA , 4ML8 , 4OAL , 3KJM , 2QKN , 2QPM , 5HQX , 5HMR , 6YAO , 6YAQ , 6YAP ), nucleoside-N-ribohydrolase (NRH, PDB ID: 4KPN , 4KPO ), adenosine kinase (ADK), adenine phosphoribosyltransferase (APRT), and histidine kinase receptors containing the CHASE domain. Modulation of cytokinin levels, through these enzymes, represents an opportunity to improve certain properties of agricultural crops (for example the grain yield or resistance to abiotic stress) in the future.

The research includes techniques for heterologous expression of the gene encoding the studied protein in E. coli, yeast or Arabidopsis thaliana, preparation of overexpressor or knockout lines in the moss Physcomitrella patens in collaboration with the University of Hamburg (Dr. Klaus von Schwartzenberg) or X-ray crystallography in collaboration with IJPB at INRA Versailles (Dr. Pierre Briozzo) and I2BC at the University of Paris-Saclay (Dr. Solange Moréra). In the case of enzymes, the kinetic parameters of substrates and inhibitors are analyzed; the binding parameters between protein and ligand are studied using small-scale thermophoresis (MST). Other techniques include qPCR methods to monitor changes in the gene expression, site-directed mutagenesis is used to study the binding- or active-site of protein, nano differential scanning fluorometry (nanoDSF) is linked to protein stability studies, and CD spectrometry is used to study secondary structures in proteins.
